in the original conditionleft by casting the ingot, or is reduced'by longitudinal rolling (so that it has a longitudinal grain),

such body having a lateral flange or flanges produced by transverse rolling, so that the grain thereof is transverse.

The invention may be applied to a cast;

steel ingot, or this may be reduced by longitudinal rolling in the ordinary manner to a bloom or other elongated steel shape. Or any suitable form of Wrought iron may be used; for example, muck bars rolled'into a bloom of proper sectlonal area whlch may or may not be further reduced by'longitudinal rolling. r i

According to the present invention the in: got, bloom or other elongated shape of iron or steel, is placed on a support and rolled transversely to cause the portion thus rolled to extend beyond the body of the steel or iron shape to form a lateral flange. The support maybe any suitable bed or table adapted to support the ingot or other steel shape, not only underneath but also laterally to the necessary extent, while it is sub-* jected to the action of a roll over it, ex tending parallel or nearly sowith the steel shape and moving relatively to the support, so that the rolling action is transverse to the longitudinal dimension of the steel shape. For this purpose either the roll may move over a stationary support, or preferably the support is formed as a movable bed which travels beneath the sta tionary roll. The supporter bedis formed with transverse grooves or depressionseach suitably shaped to receive and substantially conform to the under portion of the steel shape, which however is only partially embedded in the depression, its upper portion projecting above the support, so that the rolling operation takes effect solely or chiefly upon this protruding portion, whereby it is spread laterally to form a flange or flanges. After the upper side of the steel shape has thus been laterally flanged, it may be inverted in a suitably shaped recess and its under (now its upper) side may be similarly flanged. The laterally rolled or flanged shape may then be subjected to further longitudinal rolling, whereby toreduce its section to the desired finished contour. Or the flanged shape may be finished by forging,- bending or other metal-working process.

.The present invention enables a great variety of beams, girders, columns, and

other forms of structural steel to be rolled, 7

having flanges of far greater width than could. possibly be produced by longitudinal rolling, and renders feasible the production of various sections that it would be impossible or impracticable to produce by longitudinal rolling alone.

' Referring to the accompanying drawings,Figure 1 is a vertical section in the plane of the travel of the bed, showing a' rolling mill adapted to the practice of the present invention, and showing the steel in successive stages of the process of rolling; Fig. 2 is a fragmentary section in the same plane showing the bed adapted to further stages in the process of rolling; Figs. 3, a and 5 are perspective views of the ingot or bloom before rolling, and of the flanged products made therefrom; Fig. 6 is an elevation of longitudinal rolls for the subsequent reduction of a transversely. flanged shape such as is shown in Fig. 5; Fig. 7 is a vertical section showing a fragment of Fig. 1 01' Fig. 2 and illustrating a further modification of the bed; Fig. 8 is an elevation of and an upper or grooved plate 1), which I latter may be made in sections to advantage, three of such sections being. shown at D. The bed is preferably made to travel beneath the roll B, for which purpose it may advantageously be supported on rollers E E beneath. The roll B may be supported in any suitable side frames or. housings F, and to reinforce its middle portion against deflecting strains it may have an auxiliary roll G mounted above it. The bearings forale roll B (and r011 e if used) should be vertically adjustable as by means of any known or usual adjusting screws H, or by any other suitable means.

.gFiig. 3 shows ametal shape a upon 'WlllCll; the; transverse rolling operation 1s to be performed. This may be thecast ingot, or a' bloom or other shape reduced from an ingot, ortrom'mucli bars'or the like, by any suitable hammering, rolling or other reducing operation. Whether the transverse rolling of thepresentinvention is performed upon a cast ingot, or rolledbloom, or other shape,

will depend. upon the purpose to be fulfilled.

.The original steel shapea, is pl'aced in a V groove or depression L torinedin theto'p of the support or bed A, this groove being preferably as close'afit as practicable with the sidesofthe steel shape, and oii'a dept-h such as to leave a portion thereof projecting above the top' oif' the' bed as shown: By use of ase'ctional bfitl'tllfi shape may be'clainped tightly in the groove by means of. any clamp-- ing device, .such as screw M. The bed is then movedunder the roll 'B,which is adjusted'downward so as to bear-uponand lat' 1 erally displace the upper or protruding portion otthe steel shape a. After each pass beneath the roll, the roll is adjusted lower so that by a succession of passes the protruding portion 'oi the' steel shape is displaced laterally to *form a flange Which is spread over the u per surface of the bed. At 7) in Fig. l is shown the steel shapeatter being rolledtr'ansversely to form a flange 0 prov longitudinal 'g'rainiresulting from an initial rol-llngf, and,by ts flange '0 having a trans- ,T verse grain produced by the rolling action of face tinting in Fig. t.

. If it is desired to form a flange 0 on both sides. of the original shape whereby to produce a product such as that shown in Fig. 5,

this is performed by turning over the shape b d or 0 (Fig. 1), placing it inverted'in a suitablysh-aped recess L in the same or anotherbed (seabed A Fig. 2), and then rolling what was formerly its lower but is .now its upper side to form the additional flange, the latter beingshown at f in'Figs. .2 and b. Forconvenience in entering the shape into' the recess L this is best made with its lower enlargement deeper than the width'o'f the flange a, the excess being filled by a wedge or filling piece 0.

The modified orflanged ingot or bloorn produced by this invention, examples of which are shown in Figs. t and 5, may have its-body portion and flange or flanges variouslypropo'rtioned according to its intended 'pur'pos'e. Such modified ingotor bloom may be subjected to any desired orappropriate subsequent manipulations according to the article that it is desired to produce. For eX-" ample, it may be subjected to subsequent longitudinal rolling between such rolls as those shown at Ft.) in Fig. (3, these particular rolls being adapted to act upon the steel shape showninFig. 5 (or that shown at g or it in Fig. 2) for reducing its section to the final section desired, thereby proportionally'elongating it. For this purpose the rolls have passes R, S, T, U, adapted to suecessively reduce the section.

The improved process is adaptable to the production of sections having excessively wide "or deep flanges, such for example as that shown atinFig. 7. For such sect-ions itis'only neoessarythat the bed be constructed with its sectionsotproper shape to form intervening groovesct the requisite contour. The section a maybe reduced originally from the ingot a Fig. 1, or from an already Trolling in'a closed pass between rolls such as are shown in"Fig.f6, the longitudinal rollingis best performed by a tour-roll mill such as shown in Fig. 8, having opposite rolls P P" entering between the flanges against the web portion, and lateral rolls V V engaging the outer faces of the flanges and reducing them against the side faces or. 'io'r'm'ersfo'f the rolls P P. The latter may be horizontal rolls, and the rolls V V may be vertical rolls, or vice versa. The rolls shown in Fig. 8 are adapted torreducing the section i'shown in Fig. 7. The respective rolls may have projections or torme'rs "adapted to indent, bend, flange, or

dth'erwise change the shape of the web portion "or flanges as desired. An example of 1 this is shown in Fig. 9,where the rolls w w serve for bending out the flanges against the rolls Y Y, which latter have angular formers adapted to shape the flanges, and also to turn their outer edges against the sides of the rolls W to form edge flanges thereon. The flanged section is shown in Fig. 9 is useful as an integral column, and is a section which it would be extremely difficult or impossible to produce by ordinary longitudinal rolling methods.

The present invention is related to that set forth in my application No. 177,989 filed October 21, 1903, which however was directed more particularly to the re-rolling of old or worn rails, beams, girders, etc., for producing various laterally flanged shapes. In thatapplication the process is performed normally upon steel already reduced by longitudinal rolling, and after the transverse rollingprocess has beencompleted normally no further longitudinal rolling is per formed. The process of the present invention starts with steel or iron in substantially a raw condition, that is to say, in the form either of the original ingot, or of a bloom or billet, or other crude shape produced by an insignificant amount oflongitudinal rolling, the major portion of the redistribution required to produce the desired shape being performed by transverse rolling according to the process of the present invention, after which any desired further reduction, elongation or bending to produce the ultimate section may be performed by longitudinal rolling, or by bending, forging or other means.

Where the process is applied to a cast steel ingot, it has the additional advantageous effect of compacting the surface'of the ingot so as to close the blow holes which ordinarily lie near the surface, and to close any central voids in the ingot such as sometimes exist by reason of the failure to crop off the entire pipe. Occasionally, although the end of the ingot, after cropping, looks solid, there is some slight piping below this end, and the present process compacts the ingot so as to close any such pipes.

Though I have described withgreat particularity of detail certain processes and products embodying this invention, yet it is not to be understood that the invention is limited necessarily thereto, since various modifications maybe made by those skilled in the art, without departing from the invention. I 1

What I claim is i 1.The process of treating an ingot or bloom, Which consists in holding it in a support with its sides engaged by said support and in a position in which its edge extends above said support and subjecting the exposed edge of it to a succession of transverserolling operations by a roll supported above and out of contact with said support suflicient to roll it out into a flange extending laterally beyond the body and resting on said support. V V

2. The process of treating an ingot or bloom, which consists in subjecting it to transverse rolling to upset the metal and form a flange and then reducingthe flanged shape thus formed by longitudinal rolling.

3. The process of treating a cast ingot which consists in rolling an edge of it trans .versely to points beyond the body of the ingot soas to form a flange and under sufficient pressure to upset the metal and compact the flange so as to form a lateral grain therein.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
